When the ground is hard, water runs off instead of soaking in and can wash the mulch down.&#8221;&nbsp;<\/p>    <p class=\"wp-block-paragraph\"><strong>Pro tip:<\/strong> \u201cBefore mulching a slope, I like to rough up the soil surface,&#8221; Olberding advises.

Avoid slick plastic weed barriers, as they guarantee mulch washes away.<\/p>    <p class=\"wp-block-paragraph\">&#8220;Jute netting is what we end up doing for most of our slope installs,\u201d Hock says. \u201dIt holds mulch down flat against the grade and decomposes naturally in about 12 to 18 months.&#8221;<\/p>    <p class=\"wp-block-paragraph\">By that time, plant root systems secure the soil.<\/p>    <p class=\"wp-block-paragraph\">For erosion-prone slopes, lay <a href=\"https:\/\/lawnlove.com\/blog\/lawn-care-how-to-install-landscape-fabric\/\">landscape fabric<\/a> or biodegradable jute netting before mulching:<\/p>    <ol class=\"wp-block-list\"> <li>Roll out fabric or netting over the entire slope.<\/li>    <li>Overlap edges by 6 inches.<\/li>    <li>Secure with landscape staples every 12\u201324 inches, tighter where runoff is fastest.<\/li>    <li>Cut small \u201cX\u201d openings only where you\u2019ll plant.<\/li>    <li>Apply 2-3 inches of mulch on top.<\/li> <\/ol>    <p class=\"wp-block-paragraph\"><strong>Pro tip<\/strong>: For major trouble spots, Hock recommends stapling down a layer of jute mesh every 8 to 10 inches and covering it with a coarse mulch.
